This integration removes two external resistors per transistor — four resistors total — from the bill of materials, shrinking the footprint to a single SOT-23-6 Thin package (also listed as TSOT-23-6, supplier package PG-SC74-6-1). Each NPN handles a continuous collector current (Ic) up to 500 mA with a collector-emitter breakdown voltage of 50 V — enough for 12 V and 24 V automotive loads with margin for load-dump transients. The 330 mW total power budget (both transistors combined) is the package-level thermal ceiling; derating applies above 25 °C ambient, as with any SOT-23-6 device. Vce saturation is specified at 300 mV maximum at a forced Ib of 2.5 mA and Ic of 50 mA, which is typical for a pre-biased part at moderate drive. The minimum DC current gain (hFE) of 70 at 5 mA, 5 V gives predictable on-state behaviour for low-side switched loads. ## Switching speed and cutoff Transition frequency (fT) is 100 MHz, so this part is comfortable switching PWM signals in the tens to low hundreds of kilohertz — suitable for dimming LEDs or driving small solenoids at audible frequencies and above. Collector cutoff current is a maximum 100 nA (ICBO), which matters for battery-powered modules where off-state leakage must stay negligible.","metaTitle":"Infineon BCR523UE6327 AEC-Q101 Dual NPN Pre-Biased","metaDescription":"Infineon BCR523UE6327 automotive-grade AEC-Q101 dual NPN pre-biased transistor. 500 mA collector current, 50 V breakdown, built-in 1kΩ / 10kΩ resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q101","Package":"Bulk","Power - Max":"330mW","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6 Thin, TSOT-23-6","Product Status":"Active","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"1kOhms","Frequency - Transition":"100MHz","Supplier Device Package":"PG-SC74-6-1","Resistor - Emitter Base (R2)":"10kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 2.5mA, 50mA","Current - Collector (Ic) (Max)":"500mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a4a356f60c00ab7a012b138b891bcee.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum collector current of BCR523UE6327?","answer":"Each NPN transistor in the dual pair is rated for a continuous collector current (Ic) of 500 mA maximum."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR523UE6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR523UE6327 when reusing this data.
